The synthesis of (S)-1-(1-dimethylaminoethyl)-2-(2,3,4,5-tetramethylcyclopenta-1,3-dienyl)benzene (HL) and its reactions with a mixture of A single-crystal X-ray diffraction study of 1 was carried out: the compound crystallises in the orthorhombic, space group P212121 (D24, no. 19) with a = 8.691(6), b = 15.803(15), c = 13.840(10) Angstroem and Z = 4; R = 0.0657.Interconversion between 1 and 2 can be effected readily using HCl or base respectively.Other aspects of the chemistry of 1 have been investigated including its conversion into a free energy of activation (ΔG(excit.)) = 67.2 kJ mol-1.In contrast to 1, the methylated derivative a hydrogenation catalyst but with prochiral alkenes the optical yields were low (
